MIC2562A-1BM-TR

Overview

The MIC2562A-1BM-TR is a PCMCIA and CardBus power controller manufactured by Microchip Technology. It features two N-channel outputs with a maximum current of 200mA per channel. The device supports load voltages of 3.3V, 5V, and 12V. It utilizes a 14-SOIC package and includes fault protection mechanisms such as fixed current limiting and overtemperature shutdown. The component operates with a non-inverting logic interface and provides status flagging capabilities.

Feature Summary

• Integrated power control for PCMCIA and CardBus socket applications
• Dual N-channel low-side switches with status indication
• Built-in overcurrent and overtemperature protection circuits

Applications

• PCMCIA card slot power management
• CardBus peripheral power distribution
• Laptop and mobile computing system power controllers

Procurement Notes

Verify the specific suffix '1BM' against official Microchip documentation to confirm pinout and electrical characteristics. Note that availability may vary as some distributors list this part as discontinued; cross-reference with authorized channels for current stock status and ensure the package matches the required 14-SOIC form factor.

Selection Notes

Select this component when designing systems requiring dedicated power sequencing for PCMCIA or CardBus slots. Ensure the design accommodates the 200mA output limit and utilizes the non-inverting input logic. Consider the thermal performance requirements given the integrated overtemperature protection feature in the SOIC package.
